About Current Use Programs
Current use programs let property owners reduce their taxes by volunteering to preserve land. A property owner's open space, farmland, or forest land is valued at its current use instead of at its highest and best use. Property taxes assessed at existing use value are lower than at the highest and best use rates.
The programs come from the 1970 Open Space Taxation Act. It encourages land and water resource conservation in King County. Resources include important wildlife habitats, wetlands and streams, working forests, and productive farmlands.
